F=kqq/d^2
so you increase qq by 2x? Has to double force.
A 2-C and a 4-C charge attract each other with a 10-N froce when placed a certain distance apart. With how much force will a 2-C charge and an 8-C charge attract each other when placed the same distance apart?
** I know the answer, but can't find out how to solve it?? **
